As materialism has its watchword in the phrase the strenuous life, so the other movement expresses its fundamental thought in the process described as spiritual knowing. It is a moderate estimate that there are not less than two million people in America who accept that term as descriptive of their thought and purpose. The strenuous life is the law of material evolution. It results in the survival of the fittest. Spiritual knowing is a process of moral and spiritual development. Its effect is to fit the human race to survive. It is a movement of the people and not of the churches. But it belongs in the churches, and will in time be assimilated by them. It is simply the spiritual gospel of Jesus the Christ, which the people are rediscovering and applying.
